ethrex

We're grateful to see @ethrex_client becoming part of your infrastructure. A meaningful milestone for the project, and another step toward a more diverse and resilient Ethereum.

Great work by @ethrex_client @class_lambda. Amazing work @Nethermind too! Ethereum is scaling.

This week's community calls are moving to Monday, July 13th. @ethrex_client goes live at 2:30 PM UTC and @ethlambda_lean at 3:30 PM UTC, back to back on X. Don't miss the updates from both teams.

ethrex v20.0.0 moves block data persistence off the hot path, reclaiming 8-11% of block time that engine_newPayload spent blocked on storage. Block bodies, receipts, and trie maintenance no longer block the validity response. They persist through an overlay after the critical path, while the newest blocks stay readable immediately, so that the delay comes off every mainnet block. Also in v20.0.0: - Mempool: contract senders rejected at admission (EIP-3607), and v1 blob sidecars accepted pre-Osaka with a relaxed pooled-tx size check - Engine API: FCUv4 targetGasLimit (execution-apis#796) - Glamsterdam BAL execution: sharded parallel storage-trie merkleization for hot contracts, and block access lists threaded as Arc to drop per-block deep clones - admin_peers now records inbound connection direction No resync needed.

ethrex public devnet coming soon 👀

We wrapped up our community call and the recording is already out. All the updates on demand.

ethrex v19.0.0 fixes the P2P memory leak behind OOM crashes on long-running mainnet nodes. It also clamps snap sync response sizes, tightens EIP-7702 mempool validation, and speeds up zkEVM witness generation. The memory leak is the headline. Connection memory could grow without bounds, so nodes with weeks of uptime would slowly climb until the OOM killer took them down. The fix bounds the connection mailbox, adds lifecycle timeouts, caps peer admissions, and prunes stale connection maps. Thanks to the operators who reported it and helped us chase it down. Also in v19.0.0: - Snap GetAccountRange and GetStorageRanges responses now clamp to the server byte limit - The Engine API rejects forkchoice v3 payload attributes after Amsterdam - Mempool intrinsic-gas and EIP-7702 auth-list validation now match execution, and v1 blob sidecars are accepted pre-Osaka - zkEVM: faster execution witness conversion, with the remaining hash calls routed through the precompile We recommend operators to upgrade. No resync needed.

Our Community Call is tomorrow, live at 2:30 PM UTC. Expect a full rundown of recent progress and what we're focusing on next.
